PURPOSE:To dissipate waves having a long wave length, by a method wherein Ria barriers are mounted on the deck of a boxform structure to build a weir body, and the weir body is moored. CONSTITUTION:Ria barriers 4, each being formed such that a recess 5 is open toward the incoming direction of waves, are mounted on a deck 3 of a boxform structure 2 to build a weir body 1, and the weir body 1 is moored such that a draft line L is positioned in a level slightly lower than that of the deck 3. Waves having long wave length are rolled on the deck 3, they collide with side walls 6 of the Ria barrier 4 as the waves are progressed further deep in the recess part 5, and they are reflected in various directions to interfere with each other for attenuation, and this causes waves to be dissipated. |
